T 0 all whom it may concern:

Be it known that we, JOSEPH Gr. SMITH, a citizen of the United States,and HENRY SWARTING, a subject of the Emperor of Germany, both residentsof the city of New York, borough of Brooklyn, in the county of Kings andState of New York, have in-' vented a new and Improved Gimp or PlaitedCord Machine, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in gimp or plaited cord machines.

The primary object of the invention is the provision of a machine formaking gimp or plaited cord in which instead of covering the strands ofthe cord separately andthen twisting them together upon a separatemachine subsequent thereto, the strands, depending upon the number ofplies, are covered simultaneously and twisted so that as the cord istaken off of the machine it is completely made Without requiring theadditional twisting operation.

A further object of the invention is to provide an improved machine ofthe character described in which a pair of rotatable tables areemployed, one of which carries a plurality of bobbin holders for cottonto produce the fillers of the strands while the other carries silk orother material forming the coverings of the strands, so that as thefillers or cores are fed from the first-named bobbins they will passcentrally within the area of the other bobbins so that the coveringswill be wound directly thereon, and by means of a take-01f devicecarried by the frame of the machine, the strands will be broughttogether and drawn taut while being taken off to be wound on a reel orotherwise collected.

A still further object of the invention is to rovide a machine of thelast-named design in which the bobbin holders can be driven at variousspeeds so as to vary the degree of tightness to which the fillers aretwisted or by which said filler-carrying bobbins can be held fromrotation so that the ends or threads of the filler can be drawn offwithout being twisted, while the winding bobbins are driven at increasedspeed relative to the speed of rotation of the fillerholding bobbins soas to cover the strands tightly with the covering ends extendingsubstantially at right angles to the axes of the strands or at rightangles to the length thereof, so that the lillers will be thoroughly andcompletely covered and so twisted as not to unwind or unravel, althoughby varying the speeds of rotation of the bobbin holders for the fillersand covering threads,

' the degree of tightness at which the cord is wound can be considerablyvaried.

A still further object of the invention is to provide improved means forcausing the covering thread to uniformly feed around the fillers whenwound thereon to insure covering of the latter in the manner specified.

With the above and other objects in View, the invention resides in thepeculiar combination and arrangement of parts to be hereinafter fullyillustrated. described and claimed, it being also an object to provide adevice which is simple in construction, durable and efficient inoperation and not likely to get out of working order.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is avertical sectional view of our improved gimp cord machine; Fig. 1 is adetail View indicating the means for adjusting the finished cord guide;Fig. 2 is a. front elevation thereof: Fig. 3 is a horizontal sectionalview taken on the line 3-3 of Fig. 1; Fig. 4 is a horizontal sectionalView taken on the line 4L4: of Fig. 1; Fig. 5 is a plan view of thebobbin-carrying tables with the upper table partly broken away; Fig. 6is a plan view of the machine; Fig. 7 is a detail perspective view of afragmentary portion of the product of the machine; Fig. 8 is a detailelevation of a pair of feeding rollers constituting a portion of thetakeoff device; Fig. 9 is a detail side elevation of one of the feedingand guiding members for the silk or other covering threadsor ends; Fig.10 is a vertical sectional view thereof.

As illustrated in the drawings, the improved machine comprises a framestructure consisting of a base plate 10 preferably supported in spacedrelation to the foundation or floor as by means of a plurality ofpillars 11. The base is of rectangular form in plan and carries atriangular frame structure thereabove including uprights 12, one ofwhich is mounted at the rear corner of the base and the other two ofwhich are mounted near the side corners but slightly rearwardly thereofso that a connecting line hetween the two will be disposed rearwardly ofthe center of the plate. These uprights are braced at the top by atriangular top frame 13,the parts being suitably secured or boltedtogether, as shown at 14.

Mounted centrally on the base is a tubular support 15 having a bottomflange 16 bolted to the base while the bore of the bearing is locatedover a central opening 17 in the base so as to receive a verticalbearing sleeve 18 therethrough, said sleeve also extending through theopening 17 in the base and being held against rotation as by means ofset screws 19 extending through the tubular support 15 and engaging itsperipheral for engagement by an upwardly extending sleeve portion 25 ofthe gear 21 and of re duced diameter relative to the sleeve 22. Theseparts are supported by the engagement of the gear 21 upon the gear 26fixed to the inner end of a drive shaft 27 horizontally journaled inbearings 28 suspended from the base 10, and in this manner a positiveintermeshing and drive connection between the gears 21 and 26 isinsured. The shaft 27 carries a loose pulley 29 and a tight pulley 30 bymeans of which the shaft 27 may be driven or caused to remain stationaryby the engagement of a suitably shifted endless belt well known in thearts, although any other drive means for starting and stopping themachine may be employed without departing from the spirit of theinvention.

The base 10 supports a pair of bearings 31 thereo'ver above the bearings28, said bearings 31 having a shaft 32 horizontally journaled thereinand carrying a shiftable pinion 33 designed to be moved into and out ofmesh with a pinion or gear 34 fixed to the shaft 27 there-beneath. Theinner end of the shaft 32 carries a beveled pinion or gear 35 disposednormally in mesh with a beveled gear 36 journaled on the sleeve 18 androtatablv supported by the tubular support 15 at the upper edge of thelatter, the gear 36 being formed with a bearing sleeve 37 which isjournaled on the sleeve 18 and is formed with or carries a spur gear 38located-in spaced relation above the gear 36.

Fixed to the upper end of the shaft 20 and supported upon a shoulderproduced by a reduced portion 39 thereof is an attaching plate 40 whichin turn is bolted or otherwise secured thereto, and thus caused torotate therewith and with the shaft 20 and upper are a plurality ofbobbin holders or twisting heads in the form of disks 45, each having aspur gear 46 fixed there-beneath to its shaft or pivot and disposed inmesh with pinions 47, which in turn mesh with the spur gear 38, geared,for instance, so that each bobbin holder will rotate once for eachrevolution of the table with the shaft 20. However, to

adapt the bobbin holders or disks 45 to be driven at varying speeds, thegears 46 may be replaced by smaller ones and the pinions 47 may also bereplaced by larger ones to mesh in the same manner. For this purposethetable 42 is provided 'with radial slots 48 adapted to adjustably receivethe sleeve portions 49 of bearing plates 50, said sleeve portionsdepending from the slots and thus adapting the plates for radialadjustment to permit similar adjustment of pinions which, through themedium of their shafts 51, are journaled in the sleeves 49 and removablysecured in position as by means of nuts 52 engaged on the lower ends ofthe shafts. Thus, when the larger pinion .is used the plate is adjustedso as to bring the pinion in mesh with the spur gear 38 and the smallergear or pinion substituted for each gear 46.

Mounted on the holders 45 are a plurality of strand holders comprisingspaced vertical pegs 53 adapted to rotatably receive bobbins or spools54 carrying threads or ends to form the fillers and which is preferablyand usually of cotton. These bobbins or spools are usually held inposition by weights slipped over the pegs so as to exert tension andinsure uniform feeding of the ends which may be wrapped singly orplurally on the bobbins and which are fed through apertures 55 ofcorresponding number and location in guide plates 56 carried by theupper ends of the supports or standards 57 mounted centrally on theholders and then covered in a manner to be hereinafter more fullyexplained.

Fixed to the bearing sleeve 18 directly beneath the upper table 41 whichlooselv encircles said sleeve as shown at 58, is a spur gear 59 which isof larger diameter than the spur gear 38 and which has a sleeve portion60 forming a hub anchored to the sleeve 18, as by means of set screws61. As the sleeve 18 remains stationary and serves to steady the part,by reason of the engagement of the sleeve portion 25 of the gear 21 atits lower end, and the engagement of the plate 49 with its upper endWhile the table 41 rotates there-around, said spur gear 59, which is.

fixed to the sleeve 18, also remains stationary. Rotatably journaled inthe upper table 41 are a plurality of holders or twisting heads 62,their shafts63 being journaled in the table and removably carryingpinions 64 relative sizes of the gears or pinions, and in the presentinstance such as to rotate the holders eleven turns for each completerotation of the table in an arc of 360. By intel-changing the pinions.as heretofore described, the velocity or speed of rotation of theholders may be varied.

As the upper table sustains the weight of the lower table and the partscarried by the latter, it is desirable to provide anti-friction meansbetween the upper table and the spur gear 59 so as to permit rotation ofthe parts without undue friction. and'as an illustration thereof thespur gear 59 is shown provided with a plurality of slots 66 throughwhich project anti-friction members or rollers 67 rotatably carried bythe spur gear and in the present instance shown vertically beneath thesame in bearings 68. The strand holders comprising the bobbins or spools69 carrying the covering'strands. and each being wound with a pluralityof ends preferably of silk. are rotatably supported on pegs 70, therebeing preferably twelve of the pegs on each of the holders 45 and 62, asis shown in Figs. 4 and 5. The fillers or cores which are formed bythe'strands feeding from the bobbins 54 pass upwardly through the shafts63 and openings in the central portions of the holders or twisting heads62. and then through hollow standards 71 fixed centrally to thelast-named holders and concentric relative to the bobbins positionedtherearound. as described in connection with the supports or standards57. The standards 71 have cup-shaped heads 72 secured thereto andcentrally apertured to permit the passage of the fillers or cores 73vertically therethrough and the strands leading from the bobbins 69 areheld in spaced relation and guided uniformly around the filler byextending through notches 74 in the upper edrres of the head. saidnotches being preferably circular and provided with flared portions 75communicating with their edges to provide restricted throats preventingaccidental displacement of the strands. The strands. as is clearl shownin Fig. 10 of he drawings. extend substantially horizontally inward andare held in this position by guide plates 76 which are of circularcontour and fit in the heads 72 and hold the strands downward by theirweight. These plates, however, are comparatively light so as not toinjure the strands and are further provided with central aperturesproduced by frusto-conical extensions 77 extending upwardly and taperingin the same direction so as. to bring the silk threads of the coveringor wrapping together. as the same approach and are wound around thecores or fillers. Also carried upon the table 41 are a pluralityofangular brackets or supports 7.8 which project over each of the holdersor twisting heads 6:2 and have bifurcated free ends to rotatably supportthe grooved pulleys 79 over which the covered fillers in the form ofcomplete strands of the gimp pass, these strands then extending towardthe center of the machine and through an apertured guide plate 80adjustably carried at the lower end of a hanger 81 which is suspendedfrom the cross member of the top frame connecting the uprights disposedat the side corners of the base and thus the frame of the machine. I

The apertured guide 80 is capable of adjustment inwardly and outwardlywith respect to the hanger81 as by means of a slot and bolt connection82 so as to accurately dispose the aperture over the center of themachine when the covered strands are brought together and caused tointertwist due to the twist imparted thereto as the strands are drawnfrom the bobbins through the rotation of the holders while the tablescomprising a support therefor revolve with the shaft 20.. The guidanceof the covered strands in this manner and the exertion of unnecessarystrain upon the hanger 81 in such a manner as to cause undue tensionupon the bobbins of any one or more of the holders or twisting heads andthus to prevent one strand from being covered tighter than another andthereby made of larger diameter. is further obviated by a centeringstandard 83 which is fastened to the plate 40 so as to move with thetables or supports. This centering standard tapers toward its upper endand carries a pin 84 which proiects through the aperture of the guideplate 80 so that the ble rotates around the pin where the cord isrelatively held from rotation. passes upwardly in' a line of the centerof the machine. so as to clear a pair of shafts 86 and 87 which arehorizontally journaled in the opposed uprights, as shown at 88, and inrearwardly of the shafts spaced parallel relation vertically. Each ofthese shafts carries a pinion 89 which pinions are intermeshed throughthe medium of a pinion 90 carried by a sub-shaft 91 horizontallyjournaled through one upright between the shafts 86 and 87, and in ordertorotate these shafts and to vary'the speed of rotation thereof pulleys92 are fixed to the lower end of the shaft 20 to rotate therewith. Theshaft 93 is vertically journaled in the frame adjacent to the oppositeupright relative to the one carrying the subshaft 91, and in the presentinstance this shaft 93 is shown journaled outwardly of the frame andupright in bearings 94 carried by the top and bottom portions of theframe constituted by the parts 13 and 10, respectively, so that theshaft 93 is disposed 86 and 87. Grooved pulleys 95 are fixed to theshaft 93 near its lower end and cooperate withvthe pulleys 92 tointerchangeably receive an endless drive member or belt 96 for rotatingthe shaft 93 in the same direction that the shaft 20 rotates, motionbeing transmitted to the shaft 87 by a worm gear 97 cooperative upon theshafts 87 and 93 with the worm carried by the shaft 93 and the gearcarried by the shaft 87 so that the latter is driven at a relativelyslowspeed. Rotation is thus imparted to the shaft 86 through theintermeshed pinions 89 and 90 so that the shafts 86 and 87 are driven inthe same direction.

A take-01f device is provided to hold the gimp or plaited cord undertension as the 1 atter is formed so as to remove and collect or assemblethe same, and as illustrated this take-off device embodies a pair ofgrooved pulleys 98 which are keyed or fixed to the shafts 86 and 87.These pulleys are provided with a plurality of grooves and the cord,after passing over the guide pulley 85, extends downwardly and incrossed relation under and over the pulleys so as to be held undertension, the cord finally passing rearwardly and between a pair oftake-0E- rollers 99 and 100 and thence to be collected by wrapping,winding or folding in any pre ferred manner well known in the art. Theserollers are journaled in spaced vertical bearings 101 carried upon abracket 102 secured to the rear upright, and the shaft of the roller 99is extended to carry a grooved pulley 103 which is fixed to rotatetherewith and which is driven from a pulley 104 fixed to the shaft 87 byan endless drive member or belt 105 engaged around both pulleys. Theroller 99 is permanently journaled in the bearings 101 and the upperportions of the bearings are slotted, as shown at 106, to removablyreceive the ends of the shaft carrying the roller 100, and theserollers-have intermeshed pinions 107 which are held frictionally in meshas by means of a headlOS messes operating in the slots of the bearingsand exerting downward pressure on the shaft of the roller 100. Therollers 99 and 100 are provided with peripheral grooves, as shown at109, co-acting to conform to and receive the cord which is fed betweenthe rollers as the latter are driven in opposite directions tending todraw the cord, by rotation imparted to the roller 100 in the manneralready explained. The take-ofi rollers 99 and 100 serve to produce acertain draft or tension upon the finished cord to deliver the same tothe place of deposit or reel, and while the pulleys 98 act in a certainsense as tension devices to draw the work through and from the machine,they constitute means for shaping the cord and delivering it in aperfectly true and smooth form to and through the rollers 99 and 100.

In the operation of the machine as above described, with the bobbinsfilled or Wound, rotation is imparted to the shaft 20 from the driveshaft 27, thus to impart rotation to the support or tables 41 and 42composing the same. With the gear 33 out of mesh with the gear 34, thespur gear 38 will be held against rotation by the friction or resistanceoffered by the parts geared thereto, and the gears 46 will rotate asthey revolve around the spur gear 38 in mesh with the intermediatepinions 47 so as to impart rotation to the holders or twisting heads 45once for each rotation of the support. lln this manner the ends orstrands 110 which may be Wound singly or in plural upon the bobbins orspools 54, will be twisted slightly as the cord is drawn from themachine under tension, as shown at 111, where the strands join above theguide plates 56 to produce the core or filler 73. The holders 45 aredriven when it is desired'to twist the filler and produce a tight andhard or relatively stiff cord, but should it be desired to produce asoft cord like ordinary plaited cord, the pinions l7 are omitted and theholders or twisting heads 45 are not driven independently of therotation of the support or table 12 forming a portion thereof. As thefillers or cores, of which there are preferably three in number but thenumber of which may vary, pass upwardly through the standards 71, theyare covered or wrapped by the ends or strands fed from the bobbins 69due to the rapid rotation of the latter with the holders or twistingheads 62 as the upper table revolves with the support around the spurgear 59 with the pinions (A and 65 intermeshing and the latter meshingwith the pinion Gel and the spur gear 59 while the latter is heldstationary. as to the direction of the twist of the independent strandsor ends which are wound on the bobbins if the fillers or cores aretwisted or not as the latter are'wrapped by the ends or strands 112 fedthrough the It is immaterial notches 74 and beneath the plate 7 6 so asto be wound on the fillers transversely or at right angles to the lengththereof and are twisted by the rotation of the support and the wrappedfillers and are twisted together at the point where they pass throughthe guide plate 80. If the fillers are not twisted prior to the coveringor wrapping thereof, the twisting of the same after being covered orwrapped is wholly depended upon in .order to twist the' wrapped fillersand cause the cord to assume its final form, and in this case the cordwill be relatively loose and soft; but if the fillers are twisted andwrapped in the same direction due to the tables being driven in the samedirection as parts of the support, as well as the holders or twistingheads carried by said tables, the covered fillers will naturally tend tointertwist inaddition to the twisting thereof as the covered fillers orstrands passing from the guide pulleys 79 are twisted around the pin 84,As the cord is formed or made it is fed over the guide pulley 85 and fedalong by the take-off device heretofore described due to the tensionexerted thereby, and if it is desired to make the cord tighter the gears33 and 34 are disposed in mesh to drive the holders at increased speedso that the fillers will be more severely twisted prior to being wrappedor covered. 1

From the foregoing description in connection with the accompanyingdrawings it will be seen that the machine embodying our invention formsthe fillers and wraps the same with or without being twisted prior tothe wrapping and then twists the wrapped fillers together to produce thecomplete cord in a single continuous operation, and the cord is socovered and twisted as to be of uniform size due to equal tension beingexerted upon the strands forming the fillers and coverings. In thismanner the necessity of providing separate means for making the separatecovered or wrapped fillers, then twisting the same at the expense of anadditional operation, is obviated and the cost of production materiallyreduced.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is 1.
